Jack's Reef
500–1000 CE, Woodland (Eastern)
The Jack's Reef point is a thin, beautifully flaked Late Woodland arrowpoint of the Northeast and Midwest, about 500 to 1,000 CE, named after a site in New York. It is among the earliest true arrowpoints in the East and comes in pentagonal and corner-notched forms. Fine examples are collected for their workmanship.

Diagnostic traits
Thin, broad pentagonal or corner-notched arrow point with sharp barbs; very fine flaking.
Identification
Jack's Reef is thin and broad with sharp barbs and fine flaking in a pentagonal or corner-notched outline, unlike Levanna, which is triangular, and Raccoon Notched, which is narrower. Its thinness is diagnostic. Upper Mercer and Onondaga cherts are typical.
Reproductions and fakes
Jack's Reef points are reproduced because of their elegance; fakes are seldom as thin. Look for patina and light edge wear.
